Line Wrapping set to Word Wrap in Summary Buffer - how to permanently change to Truncate Long Lines?

[Rainer M Krug]

Hi

For some reason which I do not understand, the Gnus instance is always
switching back to "Word Wrap" in the summary buffer. Previously it was
staying at "Truncate long lines".

If I open a new Gnus instance, it is set to "Word Wrap", but a new
instance of emacs (same emacs.el file, same customization) is not.

How can I bring back the previous behavior line truncating mode for all
GNUS buffer?

Thanks,

Rainer.
